There's no specific number of study hours that guarantees someone will become a genius.
According to research, there isn't a magic number of hours to study to achieve genius-level status. Factors influencing success are more complex than just time spent studying. It is stated that there is no specific number of hours per day that children should study in order to become a genius like Mozart or Hawking.
Therefore, focusing solely on the quantity of study hours misses the bigger picture.
